En10025-3 S275N ndiro yesimbi

S275N simbi ndiro
Adopt standard: EN 10025-3
Kutengesa simbi giredhi: S275N, S355N, S420N, S460N, S275NL, S355NL, S420NL, S460NL simbi ndiro.

S275N/S275NL ndiro yesimbi

S275N/S275NL simbi inopisa yakakungurutswa simbi yezvimiro, iyo tekinoroji yekutumira mamiriro eyakajairwa kana yakajairika yakakungurutswa mune inokwenenzverwa giredhi yezviyo zvesimbi.

S275N simbi ndiro ine yakatsanangurwa hushoma kukosha kwesimba rekuita pane tembiricha isiri pasi pe -20 degree.

S275NL simbi ndiro ine yakatsanangurwa hushoma kukosha kwesimba rekuita pane tembiricha isiri pasi pe -50 degree.

Gnee simbi yaigona kupa S275N/S275NL mahwendefa zvakananga kubva pachigayo chedu mumutengo wemakwikwi kubva kudhipatimendi rekutengesa. Plate yega yega ine Mill Certificate Test EN 10204 3.1 kana 3.2.

Nezve S275N/S275NL ruzivo rweruzivo, tapota tarisa tekinoroji zuva mukutevera.

Iyo Chemical ndiyo yakakura kuumbwa kwekuongorora kwechigadzirwa:

The mechanical properties pa ambient tembiricha nokuda quenched uye hasha simbi ndiro

Giredhi	Hukobvu(mm)	Min Yield (Mpa)	Tensile(MPa)	Elongation(%)	Min Impact Energy
S275NL	8mm-100mm	235Mepu-275Mpa	370-510Mpa	24%	-50	27J
	101mm-200mm	225Mpa-265Mpa	350-480Mpa	23%	-50	27J

Iyo min impact simba is longitudinal energy

Chigayo chedu chinotengesa S275NL uye S275N mu EN10025-3 yakajairwa. Kana iwe uine chero chaunoda mugiredhi resimbi iyi, ndapota tibvunze isu nekukurumidza.
